To all whom t may concern.' Y

Be it known that l, EMORY GLENN SmirsoN, a citizen ci the United States, residing;A

at Detroit, in the countylot Wayne end. State of lflichigan., have invented certain new and Vuseful improvements in Door- Locks, ot which the following` is a specification.

This invention relates to automobile door locks and has for its object a lock which has not only the ordinary features of an automobile door lock but which also has a pin tumbler or cylinder lock'that 'can be set with the key from the outside loi the door to lock the door from openinof from the outside. 1 A

The lock in no Way aiiectsthe inside lever handle which may be manipulated Whether the lock is on or ed. ln fact, tl e lock is, in operation7 very similar to the ordinary night lock on a house door but the parts that accomplish the locking action are differently arranged than the ordinary night lock and the lock Yis set in the on or oil position simply by the use of the cylinder key. Y

On all but one door of a closed car a similar lock is used set in locked by a button.

In the drawingsf- Figure 1 is a rear elevation of the de tached lock showing the locking dog set to prevent the operation of the outside handle.

Fig. 2 is a similar vier:l showing how not withstanding the position of the locking dog it in no Way affects the inside handle which is in the course of operation.

Fig. 3 is a similar view showing the locking dog` turned to a position of non-interference With the outside door handle retractor. In this position the door may be opened freely from the inside or outside.

F ig. 4L is a section taken on the line 4 4 of Fig. l and showing the lock mounted on the door.

Fig. 5 is a detail in perspective of the locking dog.

Fig. 6 is a detail in perspective of the outside retractor.

Fig. 7 isa detail in perspective of the nger and disk by which the locking` dog is operated.

Fig. C is a cross-section showing; a modiied form of lock which can be used on the other` doors of a closed body.

position Y Fig. 9 is an elevation of a sedan showing the key lock on one door and the button lock on the remaining door.

a designates the lock housing which is of ordinary forni comprising a face plate and a front plate. o is the rear plate that coinpletes the lock housing. o is a sliding' bolt guided through the face plate and between. the rear plate b and the upstanding` lugs (Z of the front plate. The sliding` bolt o is provided with tivo lugs e and f. The lue' e is adapted to be'enke'apjed by the inside lever g and the lug' 7 by the retractor It which is .connected with the spindle'z'that is attached to the outside door handle y' thatmay be secured to the door trarne by the escutcheon 7c. Z is a torsional spring adapted to bear against a shoulder in the sliding; bolt and tends to project the sliding bolt outwardly as shown in Fig'. l. This forces the inside lever g up against the stop m. rlhis much or the construction is a conventional lock construction now in, use in automobile body construction. Y

rlhe improvement consists Vin the locking devices by which the sliding' bolt may be locked against retraction by the turnino` ot the outside handle. This is` accomplished bv the use ot the locking dog a detailed in Fig. 5 which has a turned-up lip o adapted to be ennatged bv the finger o (Fig. 7) on the rotating disk 7 which is rotatablyr sup ported in the front plate of the housing a bv turning over the edges s of the hub portion. The aperture throufrh the hub portion is square and adapted to take the squared reduced end t or' the extension spindle a secured to the end ot' the barrel et the cylinder or pin tumbler lock 'u l't is Well known that a kev oi the cylinder or pin tumbler tvpe of lock requires to be turned through a complete revolution before it can be withravvn. Ordinarily the key only turns one Way and is turned for the purpose of retractingthe sliding bolt. Here the purpose of the cylinder lock and key is simply to turn the lockinor dor In, to a position of interference with the retractor h. as shown in Figs. 1 and 2. or to a position of non-interference with the retractor 7a. as shown in Fig. 3. This is done by turning' the cylinder key in one direction or the other through a complete turn. For instance. if it is desired to set the lock on the outside handle9 from the position of the parts as shown in Fig. 3, the disk r is turned clockwise, When viewed from the position shown in Fig. 3, While the key, considered from the outside of the door, would be turned Counter-clockwise. rlhis Would bring` the parts to the position shown in F ig. 1 after a complete turn has been made. The key may then be .Withdrawn The looking dog obviously has no elieet on the inside handle, as is clearly shown in Fig. 2, Where the inside handle is heing'aetuated.

The great advantage of this lock is that the owner can always keep the loolron his closed ear door and all he has to do is simply leave the ear and slam theV door shut, and if at any time he desires to take the loeloilf, all he has to do is to insert and turn his cylinder key.

The look as described could, oi course, be placed uponlall the doors of a Closed ear, but it is preferable-to omit the cylinder lock o n all but one door and operate the disk 1 simply with abutton c@ on the inside oli the door, as shown in Figs. 8 and 9. Hence any door can be used for egress but only one can he unlocked lfrom the outside.

What I claim is:

1. In aV lock, the combination of a housinghaving parallel front and rear plates, a bolt slidable in.. said housing, an inside lever for independently retracting said bolt, an outside spindle provided with a retractor for retraeting the bolt independently of the inside lever, a dog pivoted to the inside of one of the above mentioned housing plates,the said dog having a portion swing-- ing` in the same plane-as the outside spindle retractor and havingthe swinging arcs ofthe dogandretraetor intercepting, the dog capable of being set to prevent operation of the retractor, but permitting the retraction of the bolt by the inside lever and also by the shutting of the door, a disk pivoted to the plate carrying the dog, a. cylinder look for insertion in the outside of the door, a connecting` spindle from the look cylinder having' a detachable but rotatable Y connection With the said disk, and a oonneetion between vthe disk and dogg` involving lost motion to permit the extraction of the key from the lock but serving' to actuate the dog to turn it from position of interference with the retraetor to position of clearance or vice versa.

2. lin a loel, the Combination of a housing having` parallel iront and rear plates, a holt slidable in said housing, an inside lever or'independently retracting said holt, an outside spindle provided With a retractor for retraoting the bolt independently of the inside lever, a dog pivoted to the inside of one of the above mentioned housing plates, the said dop; having a portion swinging in the saine plane as the outside spindle reti-actor and having the swinging aros of the dog' and retractor intersecting, the dop; being' capable of being set to prevent operation of the retraetor but permitting the retraction of the bolt by the inside lever and also by the shutting of the door, a disk provided With a inger and pivoted to the plate Carrying' the dog, a cylinder lock for insertion in the outside of the door, and an actuating connection between the finger of the disk and the dog permitting the linger to rotate through a large part of a turn in lost motion to permit withdrawal ofthe lrey.

ln testimony whereof l aliX my signature. v
